Short summary
The experimental and numerical simulation results of lidar sensing ahead of the airplane's flight direction were analyzed. Pitch angle fluctuations, even when compensated for within the error limits of a typical beam-steering system, can produce significant fluctuations in the backscattered signal. This effect appears in the presence of aerosol clusters with vertical size of about a few hundred meters. A simple criterion to distinguish these fluctuations from aerosol evolution is suggested.
